    Simulation-Based Retrofitting of an Educational Building in Terms of Optimum Shading Device and Energy Efficient Artificial Lighting Criteria
    (Znack Publishing House, 2016) Bayram, Göze; Kazanasmaz, Zehra Tuğçe
    The high level of daylight performance is crucial to increase academic and work performance of students and staff in educational buildings which are mostly used during the daytime. New design solutions have potential to reach optimum lighting conditions and minimum energy consumption. So, the purpose of this study is to evaluate and propose an energy efficient lighting design for an educational building. The aim is to find the optimum type of shading device with appropriate slat angles, transmittance of glazing, and the luminaire type/layout as well. Utilizing DIALux simulations, scenarios for combinations of these inputs are tested for classrooms, offices and a laboratory, which are non-identical due to their orientation, size, window characterization and facade organization. The procedure covers all significant days (winter/ summer solstice and equinoxes) during one year. Such an integrated approach would be proposed for lighting design and retrofit applications. © 2016, LLC Editorial of Journal “Light Technik”. All rights reserved.

    A Transdisciplinary Approach on the Energy Efficient Retrofitting of a Historic Building in the Aegean Region of Turkey
    (Elsevier Ltd., 2015) Şahin, Cem Doğan; Durmuş Arsan, Zeynep; Tunçoku, Selim Sarp; Broström, Tor; Gökçen Akkurt, Gülden
    Abstract Buildings account for 40% of total energy consumption in the European Union, yet at the same time they have considerable energy saving potentials. Historic buildings should be treated different from contemporary ones when it comes to energy improvements. The specifications which underline historical, sociocultural and architectural values require certain care during realization of energy saving implementations to sustain these values. The purpose of this study is to demonstrate how the energy efficient retrofitting in historic buildings should be managed in a transdisciplinary approach with a case study conducted on the historic building in ̄zmir - Turkey. A detailed building energy simulation tool was used to determine the impacts of energy efficient retrofits. The actual energy consumption of case building was based on the utility bills regarding electricity and heating fuel consumption. Building energy simulation tool was calibrated by comparing the measured and simulated indoor air temperatures and total energy consumptions. The inappropriate retrofits, which contradict to the cultural heritage values, were eliminated with a transdisciplinary approach. Later appropriate retrofits were gathered into three packages to evaluate their effects on the energy consumption. The results show that energy saving of more than 34% can be obtained without damaging the heritage values.
